Try filternulls(). Additionally, we use a custom rule filterblanks() defined as:

=remove(ri!array,wherecontains("",ri!array))

Check out the reject() function. That achieve what you're looking for.

As Jacob says, reject() is what you're looking for - but surely you should fix the issue in the expression rule rather than just removing the nulls?

If it is a List of Text and if you have Appian Common Objects you can use rule!APN_isBlank. Otherwise, you will need to write a rule that checks for an empty string or null.

Using difference( pv!array, { null() } ) should also work and perform better.
